a hotdog cannon shoots a hotdog straight up in the air with an initial velocity of 30 m/s. how high will the hotdog fly?

We have that for the Question " A hotdog cannon shoots a hotdog straight up in the air with an initial velocity of 30 m/s. How high will the hotdog fly?" it can be said that How high  the hotdog will fly is

s=45.91m

From the question we are told

A hotdog cannon shoots a hotdog straight up in the air with an initial velocity of 30 m/s. How high will the hotdog fly?

Generally the Newtons equation for the distance is mathematically given as

v^2=2as

Therefore

v^2=2as

30^2=2*9.8*s

s=\frac{30^2}{2*9.8}

s=45.91m

Therefore

How high  the hotdog will fly is

s=45.91m

At its peak height, the hotdog will have no vertical velocity, so that

explanation:

wind is defined by the direction it blows from.   for example, a wind blowing from north to south is called a northerly wind.

answer: the correct answer is 1.

explanation: there are various process in which a radioactive nuclei decays:

1) alpha decay: in this process, a heavier nuclei decays into lighter nuclei by releasing alpha particle. the mass number is reduced by 4 units.

2) electron capture: in this decay process, a parent nuclei absorbs an electron and gets converted into a neutron. simply, a proton and an electron combines together to form a neutron. mass number does not change in this process.

3) gamma ray emission: it is a decay process in which an unstable nuclei gives excess energy by a spontaneous electromagnetic process. this decay releases . this process does not change the mass number.

4) positron emission: it is a type of decay process, in which a proton gets converted to neutron and an electron neutrino. this is also known as -decay. in this the mass number remains same.

from the above information, we see that only alpha-decay is producing a change in the mass number of the nucleus.
